To @ZZ wlw/m, t may concern: j

Be it known that I, HERBERT E. Kriteriu- Lon, a citizen of the UnitedStates, residing at the city of Maplewood, in 'the county of St. Louisand State of Missouri, have invented a new'and useful Chair Desk, ofwhich the following lis a specification.

My invention relates to improvements' in chair desks, and moreparticularly-to a chair leg anda desk attachment, having a support overthe leg, capable of a wide range Yof adjustments relative to' the chairseat for adaptation toV many individual requirements and also capable offolding` over the leg to occupyv a minimum of space when vnot in use.

My object is to provide a chair desk, of simlple,'durable andinexpensive` construction,

whose top may be raised or lowered, its fwriting angle selectivelyvaried, its position respect to the seat and `which may be'bo'dilyfolded to occupy a substantially-vertical position to one side of thechair leg in front of the seat, whereby the desk may be readily adaptedto the users individual require-1 ments,I shifted to clear thespace infront of the chair and folded to permit the bringing together of aplurality of similarly constructed chair desks.

My improvements consists in the novel construction, arrangement andcombination of parts as hereinafter fully, clearly and concisely setforth, definitely pointed out in my claims and illustrated by theaccompanying drawing, in which- Fig. 1 'is an elevation of a chair deskembodying my improvements, with the top in writing position.'

Fig. 2 is a front view of the chair desk with the top folded tonon-,using position.

Fig. 3 is a perspective view of the chair leg which constitutes asupport forv the desk.

Fig. 4 is a perspective view of a fixture which is secured to the leg ina manner to be adjusted vertically, horizontally and angularly relativeto the leg.

Fig. 5 is a perspective view of one of a pair of standards over whichthe desk is mounted.

Fig. 6 is a perspective view of the slotted mounting for the desk, and

Referring by numerals to the drawings, y10 designatesthe chair,- whoseseat -11 isprovided adjacent its front, right hand corner with aforwardly projectingextension 12 and whose round, or equivalent,- 13carries .@tenon14.' V

The numeral15designates aspecial chair leg of oblong section, having alheight greater 4than the chair seat,fand arranged for connection withthechair .properI by means .of the recited extension 12 and tenon 14,asbest shown in Figs; 1 and'2. q

In its forward and rearward margins jinterjacent the plane of the` chairseatv 11` and the upper margin 'the chair 'leg 15 is provided with boltopenings 16 havingvert-ical trendsand for-'a reason hereinafter finade'clear the forward margin, as at l17, is inclined .upwardly andrearwardly .from the forward bolt opening 16. y

yBy preference the bolt openings' 16 are formed as simple notches in thechair-leg and-in order to retain bolts therein Iprovide keepers 18 intheform of simple metal-l lic straps, securedbyscrewsover' the notches.

The numeral 19 designates a'sleeve of rec-` tangular, yoblongsection,'who`se -minor dimension is 'comparable with thevthickness `ofthe leg 15 and who'se major dimensionis 4 greater than the spaoingoflthe loolt openings 16, whereby the sleeve, when fitted over the leg,will be capable of movements vertically, forwardly and rearwardly and`angularly relative to the leg, but, be held against lateral cantingthereover,

`lin each side of the sleeve there is formed a pair of slots 20 for thereception of the bolts 21 which extend through the openings 16 in theleg and which are provided with hand wheels 22 whereby the sleeve may bereadily selectively positioned relative to the leg. 1

At each of its ends, that is, forward and rearward faces, the sleeve 19carries a standard 23 which rise to heights above the chair leg 15 andwhich are perforated, to providey bearings 24, adjacent their upperends. EX- tended through the standards and supported by the bearings 24is a bolt 25 havinga hand wheel 26which constitutes a support for thedesk top.

The top is preferably constructed of wood iook and equipped kwith thevordinary appurtewith warp rails and the like, as are common, which werenot deemed necessary to illustrate.

F iXed to the underneath face of the top is a pair of parallel sills 80arranged for fitment between the standards 23 and which bear the slots31 to receive the bolts 25.

By preference the two sills are constructedv as a unit, and of sheetmetal, whereby they may be made. of relatively light material, berelatively trussed and serve as warp preventing means for the woodendesk top.

By referring to Fig. 1 it will be obvious that by reason of Athe clampbolts 21, the bolt openings 16, in the chair leg and the slots 20, inthe sleeve 19, that the height of the desk may be varied; that the desktop may be positioned and held in a horizontal position or at selectiveangles relative to the horizontal, and that the desk top may be movedand held in selective positions vforwardly and rearwardly with respectto the chair seat. The recited margin 17 of the chair leg allows amaximum rearward swing of the forward standard 23.

By referring to Fig. it will be obvious that by reason of the standards23, clamp bolt 25 and slotted sills 30 that the desk top may be swungbodily from writing position, as in Fig, 1 to a position along the sideof the chair in front of the seat, leaving the space, in front of theseat, clear and permitting close grouping of a number of similarlyconstructed chairs.

At the 'top of the sleeve 19 there are the laterally extending anges 32and 33, the former coacting with the sills 30 to prevent the sills from.coming in contact with the leg 15 when the top is folded over the legto non-using position, as best shown in Fig. 2.

The flange 33 coacts with shoulders 34 on the sills 30 to preventlateral displacement of the desk top when the same is in writingposition (as shown by'broken lines in Fig. 2)A and it is to be observedthat the sills are both supported over the top of the sleeve 19 and heldagainst rocking thereover downwardly and to the left hand side of thechair leg, but, are free to be lifted and turned on the bolt 25 to theirfolded position vertically along the side of the chair leg. n

Having'thus described my invention, what l claim as new therein anddesire to secure by Letters l Patent of thek United States, therefor,is-

1. ln a device of the class described, a leg having a bolt openingtherein, a iitting having a bolt opening therein disposed at an anglerelative tothe bolt opening in the leg, means extended through saidopenings for clamping the fitting to the leg, a bearing car'- ried bythe tting, a slotted sill and means for pivotally 'securing the sillto'said bearing.

2. ln a. device of the class described, a leg of oblong section, asleeve forlitment thereover, there being openings having relativelyangular trends in lsaid leg andy sleeve, a clamp comprising an` elementfor. extension through said openings, standards, having bearings, risingfrom said sleeve, a sill, and means for pivotally securing the sill andstandards relatively. f

3. A desk attachment for chairs, comprising a fitting, means foradjustably securing the fitting to the chair, a sill for supporting,

the desk top, means, Acomprising a clamp, for pivotally securing thesill `upon said fitting, and'means forlocking the sill against lateralmovement over said fitting.
